that the same can be reamed in a more efficient manner and at less cost than has heretofore 10 been necessary.

Another important object of the invention is to provide a portable reaming device of the character described wherein adjustments may be made to accommodate various sizes 15 of stands. a

These and numerous other important objects and advantages of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter.

Referring to thejdrawings, wherein like numerals designate like parts, it will be seen that 5 denotes a stand such as is employed for supporting rolls in spinning machinery.

' Each roll stand comprises a base 6, a standard 7 on the base, an upwardly extending oblique and slotted plate or shelf portion 8 V at the upper end of the standard and a bearing 9 at the lower end of the plate 8. V

The bearing 9 is so constructed as to provide a flange 10 disposed on a plane at right angles with respect to the plate 8. It is the bearing structure 9 that the present device is adapted to ream sothat the rolls of the spinning machine may be properly alined.

The invention includes a motor platform 11 provided with a reinforcing flange or flanges 12 and upon this platform is mounted the elec tric motor 18. The platform 11 is provided at one side withan elongated extension which is first disposed upwardly as at 14 and then declines outwardly as at 15. The extension is then disposed upwardly as at 16 at a right angular degree with respect to the declining portion 15. The declining portion has an opening therethrough for receiving bolts 17, which bolt extends through the slot of the stand plate 8 and is provided with a nut 18 whereby theaforementioned extension of the motor platform may be snugly se- 7 cured to the plate 8. A plate 19 is disposed across the top of the upright portion 16 and has its longitudinal edge portions disposed inwardly to provide guideways for the slide 20 of the reamer carrier. 6

The reamer carrier is denoted generally by numerals 21 and includes an elongated barrel 22 secured to the outer end of the shank 20 and at right angles with respect thereto and in disposition in parallelism with respect to the upright portion 16 of the platform extension. The barrel 22 is provided with a protuberance 23 at one side through which the set screw 24 is feedable. This screw has a pintle extension 25 at its free end, while Each of the members 31 is provided with I a longitudinally extending slot 33 receiving a screw 34 carried by the lower member 35 which is provided with a tongue 36 thereon slidably engaged in the groove 36 of the plate 31. By tightening the screw 34, the adjustable member 35 may be clamped against the stationary member 31 of the gauge so as to maintain the two parts in adjusted position. The purpose of the depth gauge is to limit the cutting depth of the reamer so that the roll bearings of all of the stands may be reamed to the same depth. As is apparent in Fig. 5, the plates 31 are secured to the bearings 29 by screws 32 and the members 35 when properly adjusted on the plates 31 will limit the downward movement of the reamer, by engaging the frame of the ma chine, which is not shown in the drawings.

The tube 27 is internally threaded to receive the feed screw 37 which is journalled through the upper end of the barrel 22. Suitable stop collars 38 and 39 are provided on the screw 37 on the inside and outside of the barrel 22 respectively. The outer end of the screw 37 is provided with a turn bar 40 and a handle 41 thereon.

Theslide 20 has an upstanding protuberance 43 thereon with a threaded bore therethrough for receiving the feed screw 44. This feed screw is provided with collars 45 and 46 at the opposite sides of the bearing block 47 on the upper end of the guide plate 19. The outer end of the screw 44 is provided with a turn bar 48 and a handle 49 whereby the screw may be rotated for feeding the slide 20.

The reamer 30 has a shaft 50 projecting therefrom and through the bearing 51. (See Figure 4). The outer end of the shaft 50 is provided with a bevel gear 52 and this is adapted to mesh with the bevel gear 53 on the adjacent end. of the shaft 54. These gears are maintained in mesh by means of bearings 5555 joined together by the arcuate connection 56. An angularly shaped guard plate 57 serves to protect the gears in the manner clearly shown in Figure 2.

The armature shaft 58 of the motor 13 is disposed through the bushings 5959. These bushings are disposed through openings in opposite side walls of a housing 60 and are each provided with an inwardly disposed sleeve 61 for receiving one end of the tubular shaft 62. This shaft has a gear 63 secured thereto by means of a set screw 64 and this gear is in mesh with the worm 65 on the free end of the armature shaft 58, which shaft projects through one wall of the housing 60, in the manner as shown clearly in Figure 7.

The shaft 58 is journalled through the body 6666 on the housing 60. The top of the casing 60 is open and normally maintained closed by a cover plate 67. The shaft 54 on which the bevel gear 53 is keyed is grooved at its opposite end portion as at 68 and slidably disposed through the tubular shaft 62, to receive the pins or keys 69 carried by the shaft 62.

The motor platform is provided with a pair of adjustable supports each designated by numeral 70. Each of these adjustable supports includes an externally threaded body 71 adj ustably disposed through the platform 11. This body 71 is provided with a bore 72 extending longitudinally therethrough and communicating with a counter bore 73 at one end thereof. The counterbore is of polygonal cross section and is adapted for receiving the polygonal shank 74 of the caster 75, the said caster including a roller 76. A pin 77 extends upwardly from the shank 74 and through the bore 22, the same having its upper end threaded for receiving the nut 78. v

It will'thus be seen that stands may be reamed in a more accurate and time and labor saving manner than could be attained through the use of conventional machines, and furthermore, it is to be understood that numerous changes in the specific shape, size and materials may be resorted to in the construction of this novel portable machine without departing from the spiritand scope of the invention as claimed hereinafter.
